UNITED STATES PATENT OFFICE. I

THOMAS GORDON, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO THE SIEMENS-LUNGREN COMPANY, OF PENNSYLVANIA WIND-CASING FOR REGENERATIVE GAS-LAMPS.

SPECIFICATION forming part of Letters Patent No. 421,698, dated February 18, 1890.

I Application filed February 4, 1889. Serial No. 298,623. (No model.)

To all whom it mag concern:

Be it known that I, THOMAS GORDON, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have in vented certain new and useful Improvements in lVin d-Oasings for Regenerative Gas-Lamps, of which the following is a specification.

In the use of inverted regenerative gaslamps provided with a chimney for the escape of the products of combustion and inlettubes for the supply of air to the flame it has been noticed that under normal conditions the chimney-draft is sufficient to draw inward a sufficient quantity of air to support combustion, but that a large volume of air flowing past the inlets tends to draw outward the entering air, and thus counteracts the chimney-draft and causes the smoking of the lamp.

It is the object of my invention to obviate this difficulty; and to that end my present that described in another application for Letters Patent of the United States filed by me in the United States Patent Office and serially numbered 249,511.

B is an air chamber surrounding the burner, into which the air flows downward from inlets in the upper part of the lamp.

O designates the escape-flue through which the products of combustion and heated air pass upward to the point of exit.

D D represent the air-inlet flues arranged vertically above the said air-chamber and around the gas-inlet tubes in the manner shown and described in another application for Letters Patent filed by me and serially numbered 261,912. At the upper ends of these air-inlet tubes are arranged injectors E,

which protect the air-inlets of the chamber 13.

F is the chimney, the'outlet end of which is protected by an ejector G of any suitable form.

WVhen the lamp is lighted, the waste products of combustion will pass upward into and through the escape-flue in the manner described in my said application serially numbered 249,511 to the outer air, thereby causing air to flow inward through the airinlet tubes D D. Under normal conditions the chimney draft is sufficient to draw in the amount of air required for combustion, but in lamps heretofore constructed it has been noticed that a large body of air flowing past the air-inlets causes the air therein to flow outward, and thus counteracts the effect of the chimney-draft and causes the lamp to smoke. In order to obviate this difficulty, I have placed the injectors E in the air-inlets, which serve to force the air inward when the wind blows upon them, and have placed 4 ejector G upon the outer end of theescape-flue,

which, when thus applied, serves to maintain the proper and requisite circulation of air through the lamp and prevent smoking and the clogging of the chambers.

Having thus described the construction and operation of my invention, I claim and desire to seizure by Letters Patent 1. In an inverted regenerative burner, the combination of a central escape-flue, an airtight chamber surrounding the burner, airinlets leading into the air-tight chamber provided with injectors operated by a current of air flowing thereby, and a chimney pro-
